I appreciate the above comments, though it's been over two months since the last one. So I am wondering if there is any new information on problems updating to High Sierra with using Pan 6.
I am also an old foggy, using Pan for 26 years since I had to switch from Microsoft File when they abandoned it. Have very very much appreciated Panorama, and used it as my main software running several businesses on it for years.
I agree with Golfersal that at our age I really do not want to relearn a program, and the old Pan has worked just fine, so what for...? But I know that soon it will not work at all on 64 bit, at which point I will leave it on this new Mac Book Pro and no longer update the OS. That is why I need to know about High Sierra, as I do not want to ruin my chance to stay put.
